When the food placing box is used, food is filled in the food placing box 7, an animal is driven into the space between the first short plate 103 and the supporting short plate 501 from the rear end of the first short plate 103, the distance between the first round shaft 109 and the second round shaft 506 is slightly larger than the width of the body of the animal, the animal can move towards the food placing box 7 after seeing the food in the food placing box 7, when the animal walks, two sides of the body can touch the surface of the friction sleeve 110 to drive the first round shaft 109 and the second round shaft 506 to rotate, the first round shaft 109 drives the third long shaft 204 and the first gear 206 to rotate through the first long shaft 107, the first sleeve wheel 201, the conveying belt 202 and the second sleeve wheel 203, the first gear 206 is meshed with the second gear 207 to drive the fourth long shaft 208 and the extrusion block 210 to rotate, the cross section of the extrusion block 210 is in a volute shape, the part, with the smallest diameter, of the extrusion block 210 in the initial state, is attached to the right side surface of the fixing short plate 211, and the diameter of the extrusion block 210, after the extrusion block 210 starts to rotate, is gradually increased, thereby increasing the distance from the long shaft four 208 to the fixed short plate 211, fixing the short plate 211, pushing the short plate one 103 to slide to the right side through the long shaft four 208 and the fixed plate four 209, the groove of the short plate one 103 slides along the rod body 102 to make the short plate one 103 move more stably, the supporting short plate 501 is fixed, after the short plate one 103 starts to slide to the right side, the gap between the supporting short plate 501 and the short plate one 103 is gradually reduced, the two sides of the animal body are clamped, the stopper 111 arranged on the friction sleeve 110 is in the shape of a flat-top pyramid and the flat-top tip faces to the outside, when the two sides of the animal body are clamped, the flat-top tip of the stopper 111 can generate less stimulation to the animal skin, as the animal continuously moves and the short plate one 103 continuously slides to the right side, the stimulation of the stopper 111 to the animal skin is gradually increased, so that the animal can gradually adapt to the change of skin feeling before pricking, because the stopper 111 tip is flat-top, make dog 111 can not pierce through animal skin and avoid the animal to produce stress response, and dog 111 can increase the frictional force between animal health both sides and the friction cover 110, avoid taking place to skid between dog 111 and the animal health, and the spring shrink makes five 503 of fixed plates can move to the right by a small margin in the two 502 interior spring retractions of spring telescopic link, avoids dog 111 to animal health amazing too big.

When the animal moves to the head and can extend into the food placing box 7 to eat food, the animal stops walking, the first short plate 103 also slides to the rightmost end, the first pad 602 clamps the two sides of the animal body, the third spring telescopic rod 603 enables the first clamping plate 601 and the second clamping plate 604 to move in a small range to adapt to the body width of different animals, the second round shaft 506 and the first round shaft 109 are positioned at the rear legs of the animal, when the first short plate 103 slides to the rightmost side, the part with the largest diameter on the squeezing block 210 contacts with the right side surface of the fixed short plate 211, the vertical rod 401 rotates to the frontmost side along with the squeezing block 210 until contacting with the switch button 402 and triggering the starting of the motor 301, the tubular body 308 is filled with anesthetic agent, the rotating shaft of the motor 301 drives the threaded rod 303 to rotate, the threaded sleeve 304 and the connecting short plate 305 are pushed by the threaded rod 303 to move towards the right side, when the connecting short plate 305 just begins to move, the thrust of the spring in the first spring telescopic rod 309 is smaller than the friction force between the through groove 314 and the needle tube body 308 and the sliding rod 313, the pressure rod 307 slides to the right along the inner wall of the needle tube body 308 for a distance, the medicament in the needle tube body 308 is ejected from the needle head on the right side of the needle tube body 308 for a part, so that the air in the needle tube body 308 is completely emptied, the step of manual injection is simulated, the air remained in the needle tube body 308 is prevented from being injected into the blood vessel of the animal to cause harm to the animal, the spring in the first spring telescopic rod 309 gradually shortens along with the sliding of the pressure rod 307, when the thrust is larger than the friction force between the through groove 314 and the needle tube body 308 and the sliding rod 313, the needle tube body 308 can only slide and can not rotate, then the needle head at the right end of the needle tube body 308 is pricked into the skin of the hind leg of the animal, because the animal is on food at the moment, and the skin of the animal body which is stimulated by the stopper 111 before the two sides of the animal body is adapted to a smaller pain feeling, when the needle penetrates the skin, the animal can keep a stable posture, then the needle tube body 308 moves to the right side surface of the fixing block two 310 to contact the left side surface of the short plate one 103, at the moment, the needle tube body 308 cannot move rightwards any more, the connecting short plate 305 continuously pushes rightwards to enable the pressing rod 307 to slide along the inner wall of the needle tube body 308 so as to push all the medicine in the needle tube body 308 into the animal body to complete injection, meanwhile, the fixture block 306 slides and is clamped into the fixing buckle 312, then the rotating shaft of the motor 301 reversely rotates to drive the connecting short plate 305 to move leftwards, at the moment, the connecting short plate 305 drives the needle tube body 308 to synchronously move leftwards through the fixture block 306 and the fixing buckle 312 so as to pull the needle out of the animal body, the problem that blood in an animal body is pumped into the needle tube body 308 due to the fact that the pressure rod 307 and the needle tube body 308 move relatively is avoided, damage to the animal is reduced, manual operation is not needed, injection anesthesia is completed through movement of the animal, the problem that the animal is damaged due to the fact that stress response is violently twisted due to pain when the animal is subjected to needle stick injection, the needle head is broken, and the animal attacks an operator due to the stress response is solved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
